I agree. Also keep in mind that under ICAO rules they are required to allow representatives from the country of aircraft design (USA) and aircraft manufacturer (also USA) to participate in the investigation:
They won't have a say in the report, but will be allowed to observe, and can write their own additional, if unofficial, reports. Traditionally, the engine design and manufacturing companies also request and receive permission to send representatives, but there is no such obligation under ICAO Annex 13.
Barring an unusual CCP exception, mainland China Covid regulations will require any country of aircraft design, aircraft manufacturer, etc representatives to quarantine for 3 weeks (first, 2 weeks in mainland Central Government-quarantine hotel plus 1 additional week in other hotel/residence). Potentially, less than ideal 3 week+ investigation observation delay.
